“…However, under outdoor installation, the operating temperature of solar cells considerably changes according to the surrounding environment, i.e., the climate in the installed area. In a tropical climate region, the operating temperature usually reaches more than 70 o C. The increase in the operating temperature leads to the decline in η mainly due to the drop in the V oc [1][2][3]. Among Si-based solar cells, bulk crystalline Si solar cells including single crystalline-Si (c-Si) and polycrystalline-Si (poly-Si) solar cells show higher η than thin film solar cells at STC.…”

“…The main reason for the lower TC for a-Si:H-based solar cells is due to their wide band gap intrinsic absorber or high V oc compared with bulk crystalline Si-solar cells. Therefore, a-Si:H-based thin film solar cells have advantages over bulk crystalline-Si solar cells for use in high temperature area such as a tropical climate region [3][4][5]8].…”

The temperature dependence of silicon (Si)-based thin film single junction solar cells whose intrinsic absorbers were fabricated near the phase boundary of hydrogenated amorphous silicon (a-Si:H) to hydrogenated microcrystalline silicon (µc-Si:H) was investigated. By varying the hydrogen dilution ratio, wide bandgap protocrytalline silicon (pc-Si:H) and the mixed-phase of a-Si:H and µc-Si:H absorber layers were obtained. Photo J-V characteristics were measured under AM1.5 illumination at ambient temperature in the range of 25-75 o C. We found that the pc-Si:H solar cells which exist below the a-Si:H and µc-Si:H transition boundary exhibited the lowest temperature coefficient (TC) for conversion efficiency (η) and open-circuit voltage (V oc ), while the solar cells fabricated at the mixed-phase of a-Si:H and µc-Si:H revealed a relatively high TC for η and V oc . Experimental results indicated that pc-Si:H which fabricated at the silane concentration (SC), SC = [SiH 4 ]/([SiH 4 ]+[H 2 ]), of 5.75% showed the highest initial η, low TC for η and degradation ratio. This material at this condition is a promising for using as an absorber layer of single junction or top cell for tandem solar cells which operating in high temperature regions.

“…An elevation of the operation temperature from 20 to 608C can reduce the solar cell efficiency by 10 %. [22,23] The cooling effect of the electrolyte would presumably lead to an increase in the efficiency of the PEC. The temperature difference between the photovoltaic cell and the PEC device has to be examined in the future.…”

Photoelectrochemical and Photovoltaic Characteristics of Amorphous‐Silicon‐Based Tandem Cells as Photocathodes for Water Splitting

et al. 2014

In this study amorphous silicon tandem solar cells are successfully utilized as photoelectrodes in a photoelectrochemical cell for water electrolysis. The tandem cells are modified with various amounts of platinum and are combined with a ruthenium oxide counter electrode. In a two-electrode arrangement this system is capable of splitting water without external bias with a short-circuit current of 4.50 mA cm(-2). On the assumption that no faradaic losses occur, a solar-to-hydrogen efficiency of 5.54% is achieved. In order to identify the relevant loss processes, additional three-electrode measurements were performed for each involved half-cell.

“…Higher temperature decreases the open circuit voltage as well as the short circuit current. As the total output power is measured by the Voc and Isc, the output power reduces [8], [9]. So it can be concluded that dust accumulation on solar PV reduces the power to a great extent and so it is very important to study the effects and solutions of dust deposition in module performance measurement.…”

A Solar panel is rated such that it can yield optimum output under Standard Testing Conditions (STC). But due to different environmental factors the efficiency of the panel is reduced gradually after installation. Accumulation of dust on solar PV panel is one such natural phenomenon. When dust accumulates on the PV panel, the temperature of the cells increases which subsequently decreases the open circuit voltage. The short circuit current is also reduced as deposition of dust causes shading on the panel surface. As a result, the output power of the module decreases. In this paper, the effect of dust on the performance of the photovoltaic module has been studied. The increase in temperature due to dust accumulation has been visualized through the thermal camera and the reduction in power has been analyzed through PSpice simulation and experimental data for the different amount of dust accumulated.
